Senior🎓
Top SchoolJean-marc Vanel is a veteran software engineer and founder with 23 years’ experience building AI-driven and semantic-web solutions, and he currently leads Déductions SARL from Paris. He combines deep open-source backend work—contributing to the eXist native XML database—with commercial engineering at MathWorks, where he helped develop an UML infrastructure in Java, C++ and Prolog. His consultancy focuses on rule- and ontology-based development (Prolog, N3, OWL, first-order logic) and practical automation of business application development via the EulerGUI framework. He emphasizes resource-efficient, standards-first solutions that avoid vendor lock-in and even translate formal specs into natural language for clients. A long-standing interest in biology databases and formal logic gives him a distinctive cross-disciplinary perspective on applying semantic technologies to real-world problems.
